The nucleus of the Seyfert galaxy NGC 1275 has been surveyed at 1.35-cm wavelength with the Haystack--Green Bank--Effelsberg--Onsala--Crimea radio-interferometer network. Its structure comprises eastern and western systems of features, separated by 0.7 pc. The eastern system has a core embedded in an absorbing medium whose electron density depends on distance L as N/sub e/approx. =4 x 10/sup 45/ L/sup -2.3plus-or-minus0.5/. The compact components, which measure approx. =0''.0001 across, have a magnetic field strength Happrox. =0.3 gauss. All fine-structure components maintain stable positions, but their brightness is variable. The radio brightness distribution is probably governed by the magnetic field structure.
